7'0 all w/lo/n. it may colo /co lie itltnown that I, l niixn l). lfiussnLL,a eitizen of the United States, and a resident of an Franrisro, in the county of San Fran cisro and State of California, have invented a certain new and useful. Improvement in Body-Bolsters and Draw-Castings for Tenders, of which improvement the folhiwing is a specification.

My invention relates to locomotive tenders of the class or type in which the tank is of cylindrical form, and is supported on a structural steel frame, and its object is to provide simple and effective means for trans ferring draft and butting strains from the draw casting to the tender frame, and im parting additional strength and stiffness to the overhanging portion of the frame between the bod bolster supported on the front truck and the draw and buffer easting, thereby preventing the drooping of the forward end of the frame and the loosening of the connections of the frame and draw casting members.

The improvement claimed is hereinafter fully set forth.

In the operation of tenders of the class above specified, considerable diflieult has been experienced in maintaining the draw castings securely in position, this being due to the fact that the buffer casting being located at a level considerably higher than that of the draw casting, in order to clear the draw'bar, a leverage action is exerted upon the draw casting which pries it loose from the. frame. A sufficiently extended pe riod of service has demonstrated that this objection is satisfactorily overcome by my invention, and that collateral advantages in promoting the strength of the forward por tion of the frame and its connection are likewise attained.

In the aeoompanying drawings: Figure 1 is a vertical longitudinal ventral seetion through the forward portion of a lvlindrical tank locomotive tender, illustrating an application of my invention; Fig. 2. a hall' front view, partly in section; Fig. 3, a plan or top view of the combined body bolster, and draw casting; Fig. 4, a vertiral longitudinal section through the same: and, l igs. 5 and 6, transverse sections on the lines o u and b b, respectively, of Fig. i

In the practice of 111) invention. referring deseriptively to the specific embodiment thereof which is herein exemplified, l provide an integral strneture, romprising a front draw (fasting, l, lorated at one oi its ends; a body bolster, 2, loeatl'd at its opposite end; and two lateral connecting mem bers. il, 2%. extending from the draw casting to the body bolster, said r'onuerling mom hers having lateral flanges, ll. 23, projei-ting outwardly at their lower ends. The draw casting, l, is of the ordinary form with an eye, 1. at its middle for the reception of a ('oupling hill 4. and the body bolster, J, is inwardly segmentallv curred on its to in (-onformitv nilh the rurvature ol' the ,"liudrieal tank. 5, of the tender. tberebv forming a seal for the forward end of the tank. 'lhe lateral llanges of the ronnw-ting members, ll, 3, extend under those of the strurtural steel frame members. (i. of the tender frame, whirl] are ordinarily olangle section. and the unitary draw casting and body bolster member is lirmly sevured to the webs and llnligrs oi' the tender frame members, by bolts passing through perforations. Il in the webs and llanges oi the ('o1)- nerting members. The body bolster is siniilarly bolted to the frame members. and is also bolted to the tank, ii.

The blnnper rasting. T. is lovated rela tively to the front draw casting. as in the ordinal eonslrurtion. thal is tosay. at a sullirientl higher level to enable it to rival the draw bar.

For new applieations, the d aw rusting, body bolster, and eonner'ling members are preferably formed in an integral casting, of the construction above desorihed, but my invention may. without variation of structural or ope 'ative principle. be applied to existing equipment, by providing separate (-onneeting members, of the angle sertion shown, and scouring them, at their ends, to the draw bar and the body bolster, by elevtrio or :u-elvlrne welding. then-b preserving the original rastings, and embodying them in an integral trln'ture. in such case, the weld at the forward ends f the eonnerting members follows the contour of the end flanges of the front draw rasting. thereby affording a weld of greater length than if made straight across the casting and correspondingly promoting its strength.

An annular wearing plate, 8. is interposed between the body bolster, 2, and the center plate, 9, of the front truck, being fitted in a central rer'ess in the body bolster. Said plate is perforated for the passage of the (-enter pin, 10, and may be prevented from turning in the body bolster, while readily removable therefrom, by a dowel pin secured in the body bolster, or in any other suitable known manner. In addition to fulfilling the function of absorbing wear, the plate, 8, serves as a shim for maintaining the tender at the proper hei "ht to comply with Interstate Commerce commission requirements.

It will be seen that, under the construction above described, such a strong and substantial connection of the front draw castin to the tender frame is afforded as will e ectnally resist the strains of draft and buffing which are imposed on said casting out of lnae with its connection to the tender frame, and which therefore tend, with an action increased by leverage to loosen it from its normal rigid connection to the frame. A more effective support for the forward end portion of the tender is also provided.

I claim as my invention and desire to secure by Letters Patent:

1. The combination, with a cylindrical tender tank, of a tender frame, and an integral structure comprising a front draw casting; a body bolster, having a curved tank seat at its top; and lateral connecting members, extending from the draw casting to the body bolster, and rigidly connected to the forward portions of the frame members.

2. The combination, with a cylindrical tender tank, of a tender frame and an integral structure comprising a front draw casting, a body bolster, having a curved tank seat at its top; lateral connecting members, of angle section, extending from the draw casting to the body bolster; and connections rigidly securing said connectin members to the frame, through their bodies and their flanges.

3. The combination, with a cylindrical tender tank, of a tender frame, comprising side members of angle section; an integral structure, comprising a front draw casting; a body bolster, having a curved tank seat at its top; and lateral connecting members of angle sections, the flanges of which fit be ow those of the frame members; and bolts, securing the connecting members to the frame members, through the bodies and flanges of each of them.

4. The combination, with a cylindrical tender tank, of a tender frame; anintegral structure, rigidly secured thereto, and comprising a front draw casting, a body bolster having a curved tank seat at its top; an lateral connecting members, extending from the draw casting to the body bolster; and a bumper casting, connected to the tender frame above the level of the draw casting.

5. 'Ihe combination, with a cylindrical tender tank, of a tender frame; an integral structure, rigidly secured thereto, and comprising a front draw casting, a body bolster, having a curved tank seat at its top; and lateral connecting members, extending from the draw casting to the body bolster; and an annular wearing plate fitted detachably in the body bolster, and perforated for the passage of a center in.
